The distance of an object moving with initial velocity $u$ and acceleration 'a' and final velocity 'v' is given by $v^2-u^2=2as$. The acceleration of the particles in terms of $u, \;v$ and $s$ is

Question

$\begin{array}{1 1} (a)\;\large\frac{v^2+u^2}{2s} \\ (b)\; \large\frac{2s}{v^2+u^2} \\ (c)\;\large\frac{v^2-u^2}{2s}\\ (d)\; \large\frac{2s}{v^2-u^2}\end{array}$
